Ok, not my favorite coloring, but I'm putting it out there anyway. I colored the pigs (My Favorite Things' Sow Much Cuteness) with Prismacolor pencils on kraft card stock. I may stick to flowers for this in the future.
I stamped an inside panel, since I used a deep brown card base, and for good measure I put a little butterfly from the same set on the inside, too. I went a little crazy and put a pig on the envelope as well.
I had a watercolor panel in shades of lilac, and I used a crazy rays stencil that I've had for a very long time to back the pigs.
